Design Blueprint: A Superconducting Radio-Frequency Cavity Thermal and Quality-Factor Budget: Surface Resistance, Cryogenic Load and Cryoplant Power

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24147831): This paper presents a computed design for a superconducting cavity intended for superconducting radio-frequency systems, with its performance, resource budgets and margins derived from stated assumptions rather than asserted. The headline results are: bCS surface resistance at 2 K and 1.3 GHz of 24.6 nano-ohm; total surface resistance including the residual term of 29.6 nano-ohm; unloaded quality Status: DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. All numbers are simulated values from the source paper's computation, deposited with this blueprint as compute.py and results.json. AI-use disclosure: Dave, an AI research system, assisted with the computation and drafting under the author's direction; author of record William Alexander Aldred.
